S 'EPAR ATOR MECHANISM FOR RING-SPINNING FRAMES.

SPEGIFIGATION forming part of Letters Patent No. 527,389, dated October9, 1894.

Application filed June 6 1894:- Serial No. 5 0 N m l-i To all whom itmay concern.-

Be it known that I, ALFRED HITCHON, of Accrington, in the county ofLancaster, England, have invented certain new and useful Improvements inSeparator Mechanism for Ring-Spinning Frames, of which the following isa specification.

My invention has reference to the separator plates used to checkballooning or interlashing of the bobbin threads in ring spinningframes, and it consists in an improved construction, arrangement andmounting of the parts whereby the space occupied by the separator andits attachments is diminished, and the separator can easily be throwninto and out of position.

My improvements can best be explained and understood by reference'totheaccompanying drawings in which-- Figure 1 is a cross sectional elevationof so much of a ring frame as needed to illustrate my invention. Fig.2is a plan of aportion of the ring rail.

In the drawings, A represents the drawing roll stand; B, the ring rail;0, the spindle rail; D, D, the lifting pokers which pass therethrough;E, the usual tin rollers for driving by cord or belt the spindles; F, F,the thread guide boards. These parts are organized and arranged toco-operate in the usual known manner, and require no furtherexplanation.

In carrying my improvements into effect I form in the back of the ringrail a longitudinal groove or concave a in which is placed the shaft orrod b on which the separators are mounted-said rod being there held bybearing straps 0 located at convenient intervals apart. The rod or shaftis capable of a movement of rotation or partial rotation, and I preferto form it in lengths corresponding with the sections of the ring railso that the separators for each rail section may be operatedindependently of the others.

The separators may be loosely mounted on their rod or may be fixedthereto. Each separator is in the form of a blade G, which is formed bycasting, stamping or in other convenient manner, and may be solid,perforated or (as shown) in the form of a grid. The blade projectsbetween two adjoining spindles, and has a downwardly extending shank g,terminating in a tubular boss 9 through which the rod b is passed-thering rail being recessed at the point where the boss comes so as topermit the latter to lie partly within it. Just above the boss is aforwardly projecting stop 9 which by bringing up against the ring railprevents the separator from falling too far forward.

I affix to the roller beam A a'downwardly projecting stop plate orplates H, back of the separators, this stop plate being inclined,concaved or curved on its front face as shown in such a way that whileacting as a stop for the separators when the ring rail is down and theseparators are thrown back for doffing as indicated in full lines on theright of Fig. 1, it will, when the rail is raised act to throw forwardthe separators into working position, as indicated in the intermediatedotted line position on the right of Fig. 1. On the left side of thering frame in Fig. 1, is shown a partly filled bobbin of yarn with itsthread being delivered from the drawing rollers and passing through thethread guide to the bobbin on which the yarnis wound during the spinningoperation. The separator is here shown in position for preventing thethreads of any two bobbins from interlashing.

The downwardly projecting shank of the separator is of such length as toalways maintain the blade itself at a sufficient distance from the ringtraveler to allow the rings to be placed in the closest possibleproximity to each other, that the working of the travelers upon twoadjoining rings will admit of. The blade furthermore is alwaysmaintained ata sufficient distance from the rings and ring rails toenable the attendant to easily finger or manipulate the ring travelerswhen piecing up or handling the threads. The blades thus located, duringthe ascent of the ring rail, may at times rise above the thread guideboard F. As this board is in their path, I form in it notches or slots ffor the passage of the blades. In the topmost dotted line position onthe right of Fig. 1, one of the separator blades is represented in theelevated position, partly received in the slot formed forits passage inthe thread guide board. By this construction I am enabled to materiallyincrease the height of the separator plate, and thus to enhance itsefficiency.

Having now described my improvements,

what I claim; and desire to secure by Letters Patent, is p 1. In a ringspinning frame, the combination with the ring rail and the separatorshinged thereto, of the curved or inclined stop plates H, located in rearof the separators and secured to astationary part of the frame,-substantially as and for the purposes hereinbefore set forth.
